Easily manage/block unused CSS/JS from loading on individual pages where all they do is create bloat and negatively impact page performance.

Scan, size, and safely block CSS/JS per page. Per-device + per-template rules, live savings counter, dry-run preview, and editor-safe mode for Elementor and other page builders.

Description

Advanced Script Manager helps you load only what a page needs and block the unused junk:

  • Lists all CSS/JS with file sizes and handles.
  • Block per device (Any/Desktop/Mobile) and per template (Any/This Template).
  • Dry-run preview (cookie-based) before saving.
  • Editor-safe: skip blocking in Elementor editor; optional per-page disable.
  • Hybrid server-side dequeue + client-side catch for late-injected assets and @import.

Installation

  1. Upload advanced-script-manager to /wp-content/plugins/.
  2. Activate the plugin.
  3. (Recommended) Copy mu-plugins/asm-blocker.php to /wp-content/mu-plugins/ for the strongest blocking.
  4. Go to Settings → Advanced Script Manager, pick a page, Scan assets, choose items, Preview, then Save.

Frequently Asked Questions

Where are the rules stored?

Per-post meta key _asm_blocklist_v1. A temporary cookie asm_preview_blocklist is used for dry-run.

Elementor compatibility?

Blocking is automatically skipped in the editor (?elementor-preview=…). You can also toggle “Temporarily disable blocking” per page.
